High Voltage DC Tester PT18-10 MK2 18kV 10mA
he PT18-10 mk2 high voltage dc test set is designed to perform tests on installed cable and jointing systems.
The High Voltage DC Tester PT18-10 MK2 18kV 10mA Tester has a variable output voltage with a maximum of 18kVdc with a maximum charging capability of 10mA. A zero-volt interlock is fitted that prevents the output being switched on unless the output control is at zero. Units include an automatic load discharge system that discharges the cable under test when the output is switched off or a breakdown occurs. Internal dumping system can discharge a maximum of 2.5kJ on each output, corresponding to 10F at 18kV. In the event of a test object failure, the overload circuit will automatically switch off the output voltage and earth the output via the internal discharge circuit. A DP20 discharge probe is supplied as standard with the PT18-10 mk2, 18kV 10mA DC Tester, allowing higher load capacitances to be safely discharged. The High Voltage DC Tester PT18-10 MK2 18kV 10mA Tester has an internal fail-safe automatic discharge system with the following ratings:
- Max. discharge voltage (kVdc) 20kVdc
- Highest discharge energy 2.5kJ
- Highest discharge capacitance 10F
- Max. discharges per hour 4
The automatic discharge switch is controlled by a solenoid. It may produce a noticeable hum when the HT output is energised. \n Output voltage is metered by two large, linear, analogue instruments marked 0-20kV. Meanwhile, current is metered by two further analogue instruments with 0-10 scale marking. The meters read 0-10mA directly, or 0-1mA when the 10 push button is operated. The HV output from the unit uses a high quality plug and socket system, allowing for easy cable replacement. High voltage plugs are protected in transit by plastic covers and are fully de-mountable. Screened 5 meter long high voltage output cables are provided with the equipment terminated with large clips. The mk2 units introduce automatic 115/230V mains voltage selection. That along the padded bag ensure maximum protection during transit.
